Decker recalls that "Voyager VI disappeared into what they used to call a black hole. It must have emerged on the other side of the galaxy." At the time of this film, black holes in science fiction, such as The Black Hole - Il buco nero (1979), were often given the properties of what are now hypothetically known as "wormholes". Black holes are now understood to be singularities; not literally holes in space, but very dense masses from which light cannot escape. However, black holes on account of their hypothesized gravimetric properties, still continue to be used as plot devices for super-luminal travel. In such cases, time dilation and other Einsteinian concepts are generally still adhered to. Wormholes (also known as Einstein-Rosen bridges) providing instantaneous long distance space travel remain hypothetical. A proper wormhole would eventually become a plot device in Star Trek: Deep Space Nine (1993).
